FYI, in the Chicagoland area all the newer Smartphones like Galaxy2, Galaxy4 and iPhone have problems staying connected or connecting to the T-Mobile wireless Network. At first I was thinking it was more localized, like maybe problem with a tower but it turned it to spread over several Zip Codes around here. Seems it doesn't affect older phones like My Touch and flip phones. The one I have mentioned can't send or receive calls, texts and the data connection is down as well. Sometimes you may see a message not registered to the network but most of the time you'll have no clue that's something is wrong. Seems like it has started over the weekend with some being affected and some not, and those affected Sunday are OK today, while those that didn't have a problem Sunday are affected today. The phone once in a while does register to the network and all those voice mails come it, sometimes it will stay on for several minutes after reboot, but the it just stops without a visible sign. Anyone else experiencing any problems with T-Mobile??? .
