    Unlock: The Galaxy S can be sim unlocked as the community found that the unlock code was stored in plain text within a particular file.

    Rooting: giving you root access to the phone.

    • Use SuperOneClick to root the phone: http://shortfuse.org/
    • You will need USB drives. I believe I used the ones which were included with the Samsung Mini Kies software

    ROM flashing

    • Instructions for installing ROM with CWM (clockwork recovery): http://forum.xda-developers.com/showthread.php?t=1215748
    • The procedure flashes a new ROM with CWM installed and using CWM to put on a new ROM.
    • Note: Recovery mode and Download mode are different. Recovery mode (up/down/power buttons pressed). Download mode (up/down buttons pressed while inserting USB cable).
    • CWM allows to install new roms/files from the SDcard while in recovery mode.

    AT&T 3G Support for T-mobile Galaxy S 4G:

    • Phone officially supports T-mobile 1700/2100 MHz UMTS Band IV (AWS), and also over seas Band I (2100)
    • Phone also supports AT&T 1900 MHz UMTS Band II (PCS) from testing with a SIM. Historically, T-mobile uses the 1900 MHz band for only 2G coverage, but has been expanding 3G services on this band. This is the cause of the resent reports of 3G data available on AT&T’s iPhones.
    • AT&T also uses 850 MHz UMTS Band V, not supported on this phone. In some areas AT&T only uses 850 MHz for 3G coverage. On my trip from San Jose to Las Vegas, I found that when there is 3G coverage, almost everywhere also had 1900 MHz coverage. The lower frequency of 850 MHz does penetrate buildings better, which can make a difference in some areas.
