i just got the grevey sim and it all worked fine in finding my carrier tmobile but the GPS does not work correctly. it will not find my exact location similar to how my 2g was where it would give me a big circle where i could be. although if i leave it sit for a while it does sometimes locate me so it got me wondering, is the the sim hack or the fact that i am on the edge network trying to use the GPS? if i take out the sim card and just use my wifi connection the GPS works fine

also as a side problem when in cydia on edge i can not download anything but i can browse the web and everything else no problem

any suggestions about either?
