Barely get my 920 Tweaked so that it is just how I like it and I see there is a 1020 ... I am a T-mobile user in the USA so I bought the Pentaband from Rogers in Canada. I haven't looked to see if the 1020 will give me 3G 4G or LTE with Tmobile USA BUT I am thinking that by the time I get an answer there will be an 1120 ... Lumia is cranking out new models faster than Apple does iPhones. My question is, are the changes worth switching? Diane
