Bell is strictly CDMA - had this same issue at least 6 years ago with motorola phones, there's no gsm unlock code, you'll find yourself if you are going the right direction with an encrypted chunk of firmware and poking around almost randomly based on others experiences with other models from bell with some crazy software from quallcomm and honestly there's no hope there... Although it looks as if i'm headed down that path again - but aside from this issue of the encrypted mystery unflashable part of the phone - is it possible the 1700L has GSM hardware that's just not used???????????? How can I be sure - i don't think the other phone flashes would work even if it did, would they?? Am I way off on this but it seems to me bell isn't involved with manufacture and it is possible - is there anyway we can put a generic phone module on there to test for the presence of the GSM hardware? Is the encrypting/decrypting part of the phone a part of the unflashable area so taht this is not possible without modifying it at the digital logic level????? I've been wondering this for too long and your comment about GSM made me laugh because I alwasy regretted having so many 'broken' bell phones and nobody with nice instructions... although these ones are GREAT and i'll suffer with bell cdma for now as i'm excited to think I could even get 2.2 was it? Is that for real or someone else that didn't see the L??
