I still think somebody needs to try and change the name of the "NWP8_simlock_3gstandard_bb5_crcA59A" in the default firmware image to the EE name and then change the reference in "RM821_059R1W4_1232.2110.1244.3011_094.v\\... I am sure it is not this easy but you never know. I am just not brave enough to do it, plus I can't get these bloody drivers sorted. First full day of use and the battery lasted about 10 hours after a full over night charge from 0% to 100%. Would definitely say it got more use than normal being a new toy and all that, but certainly nothing excessive. Was going to go for the 399 payg deal at EE but some one has mentioned that my tmobile sim would not work in it due to it being locked to Orange. I guess this is the point where I just give up trying to get this handset. Hi guys Orange payg Lumia 920's from the ee store work fine with T-mobile and ee sim cards and or 4G ready I got one yesterday from the ee store locked to orange for 399 with free charging pad and headphones. It works perfect with my T-mobile sim! Orange T-mobile and ee are all the same network and new phones from ee stores work with all 3 networks I still think somebody needs to try and change the name of the "NWP8_simlock_3gstandard_bb5_crcA59A" in the default firmware image to the EE name and then change the reference in "RM821_059R1W4_1232.2110.1244.3011_094.v\\... I am sure
