TopShelfCookieJar:kiwijunglist: ^ Check the darky forum I think I remember reading some posts about i9000T + Darky Rom
Thanks for that. Read a few posts on their forum and while they listed some fairly complex process to make 850 'stick' (flashing one modem, making some band changes, flashing another modem, making more changes, and then flashing the modem you actually want) I just tried a different modem (KC1 in this case) and I was straight on to 850 without having to make any further settings tweaks!
I'll see how KC1 goes re battery life, etc but the fact I've now got 850 connectivity makes me pretty happy.
you were using the wrong modem for XT - despite doing the convoluted process to get 850 'tickable' in the service menus etc you will still find most modems refuse to come off 2100 for XT, which is annoying. ive played this game many times - i can only attribute it to the modem file you use: id say the signal strength tolerance in each modem.bin is different, (which tells the phone when its time to switch bands)
you should be good with UGKC1 which is what ive been using for a while now and it functions great. just got back from a trip to melbourne and can confirm the same modem works very well there, 3g data and all.
