Baseband - 4.26.08
Phone is US - Locked to at&t
1 .Did ra1n install to allow Cydia install.
2. Resumed ultrasn0w install.
3. inserted t-mobile sim.
sms, mms, calls, email, data over EDGE/GPRS, GPS works, youtube, i-tunes sync.
Wifi - this was working prior to ultrasn0w.
Currently tracking battery consumption.
But with no wifi only.. this is acceptable
What i haven't tested is if wifi was working post ra1n install, to cydia install, to ultrasn0w install. I'll track this further over the weekend.
thought to post this as a success status.
