When I said "restrictions" I was talking about Androidforums.com's restrictions on posting screenshots(physical and file size).
Ok, so here we go....
First, go to this link and download the RUU(Rom Upgrade Utility)
Goo-inside.me Downloads - Downloading RUU_HOLIDAY_ICS_35_S_CINGULAR_3.26.502.52.zip
Second, you need to use HTC Sync to sync any data that you want saved.
Third, you need to connect your device to your computer, and set it to "charge only". You need to make sure that you have "USB Debugging Enabled".
- From the Home screen, press the Menu key.
- Tap Settings.
- Tap Applications.
- Tap Development
- Tap to check USB debugging.
Once you've enabled USB Debugging, and connected your device using the "charge only" setting, Double click the RUU file.
From that point on, it will prompt you for a couple things, but there are no options or choices to make. Its bulletproof.
THIS OPERATION WILL COMPLETELY WIPE YOUR ONBOARD DATA, AND RETURN YOUR PHONE TO "OUT OF BOX" CONDITION. It will have Android 4.0.3, and Sense 3.6
This is an AT&T release and does not void your warranty, unlock your bootloader, gain access to the root folder, or remove AT&T bloatware. This is perfectly legit for those who don't wish to mess with root. An RUU is the manufacturers method for upgrading phones.
I have screenshots, and just don't wanna mess with uploading them(too much of a pain). If you wanna see them, PM me and I'll email them to you.
This is painless and so worth it!!!
EDIT: This does not wipe your SD Card
