Hi,
i am new to this forum. i have a phone 3gs running on ios 3.1.3 (very old !!!). i need to update it to 4.2 or 4.3 (not jail break). I have downloaded the ipsw files for 4.3 and 3.1.3 (just in case). how do i go about upgrading the firmware. is it straight forward or do i have to go to a shop to get this done. (i read saying that on tunes shift+click on restore iphone and choose the 4.3 ipsw file and its done. is this true ?)
I contacted Apple and they say to upgrade to ios 6 which i dont want to do because my phone is just a 3gs model and it will be sluggish.
Any help please ?
Thanks
