    I have an unlocked T-Mobile G1 that I've been using on AT&T. If I do a factory reset, will it remove the unlock. Dopey me, I misplaced my original unlock code.

    Anyone know?

    Just confirmed that a factory reset does not remove the unlock. I did have to modify the APN settings to use it with my AT&T sim card. Hitting menu at the Gmail login will bring up wireless networks. Edit the APN as follows:

    apn:wap.cingular
    proxy blank
    port blank
    username:WAP.CINGULARGPS.COM
    password:CINGULAR1
    server blank
    mmsc:mmsc.cingular.com
    mms proxy: blank
    mms port:80
    mcc:310
    mnc:41
    apn type blank

    I've got an iPhone plan -- works great.
