You can't work out how to construct a sentence so please don't attempt to make changes to your mobile phone.

What give's you the ****ing right to question me and my writeing, if you don't have a comment on the matter then don't say anything at all ! Mug

Cydia sounds like some sort of bladder infection.

Bit harsh there Jack, I can make perfect sense of what it says.
Please use punctuation in your own reply, before judging others lol.

OP, why would you wanna change the theme of the phone? I thought the UI was one of the finer points. Cant say I would wanna change it myself. But each to their own I guess.

As for jailbreaking etc, there are loads of guides on the net, or people that will do it for you for very little these days.
Some say it will void warranties etc. But I could not tell ya either way.

Thanks snazy, i thought myself that it would void the warranty, guess i will leave it alone the
thanks

No worries mate, there are other threads on here about jailbreaking and the pro's and cons of doing so. Not a bad thing that I know of, but then I dont own an iPhone and am not best known for saying nice things about them lol.

With most things like that, I stick with the "if it aint broken" rule

Good luck with whatever you decide.
You could always ask Markus.

You actually need to jailbreak the phone before you install cydia. Jailbreaking allows you to add additional applications to the iPhone, things that are not in the AppStore, and Cydia is one of those things. I tend to think of Cydia as being similar to the AppStore, but not under Apple's control, and so, more or less, anyone can create an app and repository source for it and have people add it to cydia and thus download the app.

Will it mess up your iPhone, maybe, maybe not. Some people do have problems with jailbreaking, but most are able to do it without issue. I have jailbroken my 3GS, mainly just to see what the fuss is about. I'm not on O2 (I'm in Canada for a start) but my phone still retains full functionality with my cell phone carrier.

The first steps in jailbreaking your iPhone are to find out exactly what model is it (2G, 3G, 3GS) and also what OS version it is running, this can be done by going into Settings -> General -> About. It will give you a list of things, one of which will be "Version", that's the OS version.

What you can then do is pop over to iClarified and search for Jailbreak iPhone XX with OS YY - where XX is the model of phone, and YY is the OS version, for example "Jailbreak iPhone 3G with OS 3.1" and it should give you a tutorial on how to do this.

At present, if you're on 3.0 or 3.0.1 and you want to go to 3.1 and you have a 3G or 3GS then you will need to use Pwange Tool and that will ONLY run on the Mac, so if you don't have mac you might be stuck. Typically you would use PT to create a custom iphone software file (ipsw) and use iTunes to restore that custom file. I would suggest however you go and read the tutorials first to see if jailbreaking is something you would be comfortable doing.

On behalf of chelsea77, cheers Markus

thanks for your help, i will do more searching!

....... not to sure i am lol

Markus

I can fully understand. It is possible to brick the phone, making it unusable. Now, if it is under warranty you could see if you could return it and get a new one, but if they do manage to unbrick it and find you were attempting to jailbreak it, they could well refuse you a new one.

chelsea77

oh dear, i'm kind of happy with the way it is lol

chelsea77

If you can do all this to your phone why are Apple not happy with people doing this?

Snazy

I think the idea is Apple like to test all the apps and networks that the phones are being used on. That way they can be sure that the phones will run "smoothly"

With people putting on apps etc that are not tested to work and no cause issues, it can affect the reputation of the devices.
And also, anything that causes the phone to run badly or even brick, Apple or the carrier would not be happy replacing the phone as its not their fault it bricked.

If that makes sense.

Same as why car manufacturers frown on people remappnig cars, then trying to claim for a melted engine on warranty... lol

Markus

Apple likes to control as many, if not every facet of it's devices, especially something like the the iPhone. They want control over what apps are being installed on it and what those apps can do.

Here's a good example. You have a voice and data plan with your iPhone, you pay, let's say O2, your monthly fee for this. Now, you CAN get skype for the iPhone but it's telephony features will only work over wifi and not the 3G connection. Why? Well, you'd be able to phone people for free otherwise, using their 3G network, but not using their voice plan. Thus you could drop your voice plan and have just a data plan (though I don't think they allow this) and still make phone calls using the data connection over 3G.

os changes on a blackberry are nearly an everyday occurrence. we can "unbrick" a BB if the sh1te hits the fan though.

Snazy

I tend to update mine about once a month. Unless the changes in the OS are not substantial enough.
Not sure what warranty implications there are for a BB if you put a beta version on there. Not heard too many horror stories anyway.

I have just wound a few of the parts of my OS back on mine.
Just waiting on the 9700 now.

bigsinky

just restore an official 4.7 version and bob's your auntie's live in lover
