If the HTC Tilt is also an AT&T phone, then yes. There should be no problem with it.
You can reset your HTC Tilt if the soft keys don\'t work by calling customer service. The customer service agents can do a master reset over the phone or walk you through the process.

The HTC Tilt 2 unlocked can be purchased on various sites like Amazon.com and ebay.com. The prices range from $250 - $600 depending on whether you want one brand new or used. Although AT&T originally offered the service for this particular phone I do believe most mobile servies now offer service for it now.
You can use the HTC Aria with the $50.00 plan from AT&T. This phone can be used with any type of AT&T plan.
