If you're in the crowd holding out until the Samsung Galaxy Tab 10.1 hit Ma Bell's 4G network, get ready to pull the trigger. The code-named SGH-I957 rolled through the FCC sporting a label for AT&T's LTE service on its backside. It appears the carrier will offer the 10.1-inch slate alongside the similarly sized HTC Jetstream. Don't forget, the latter of the two will set you back seven whole Benjamins... on contract. The AT&T Galaxy Tab should save you a few bills, though, if the pricing is comparable to VZW's LTE offering.
