Hi, 1st time post. Just bought Unlocked HTC Hermes to connect to XT Network. Flashed a couple stock roms off internet. My question is: Is an extended rom necessary to connect to Telecom XT. Can you just install OS, delete cab files in extended rom after you ulock/unhide it & good to go. Or are there connection cabs (wizards) that get connection settings etc off the network for windows mobile. I thought I'ld just go into Telecom & try a sim in phone. I suppose that if there are Telecom Extended Roms around they are only for phones Telecom currently support/sell. Do Extended Roms address Hardware, OS or both issues. Can you do without them.
