I've got an unlocked inspire 4g from at&t, to use abroad (i am living in france). while in france i have noticed that the connection symbol is always E or G, never H, although a friend who has a shitty HTC wildfire is always on H, same network, same spot. Thinking it is an at&t bug i rooted the phone and installed a custom ROM (TPC_Inspire4g_stock_optimized_v2). all went well, except the connection did not change - it still only shows either G or E and it is massively slower than the mentioned Wildfire. what's going on?
