Can i update my unlocked iphone 3g to ios 5?

I have an unlocked/jailobroken iphone 3G on tmobile and i wanted to know of there was any way to update it to the ios 5.1.1 update so i can have ringtones and all the apps.

Did you make a backup? If yes, put the backup (without jailbreak) on it then update it and you should be fine.

Not offical… You can use whited00r 5.1 firmware for the 3g to get 5.1 features.

Go to iphoneadmin.com so you can get info on your iphone
