If you're a T-Mobile customer looking for a budget or prepaid device for messaging and email, you should circle May 20th on your calendar. BGR has a tipster who reports that this is the date when T-Mobile releases the Samsung SGH-T349. The handset offers a 20 key "SureType" typing method that we've already seen on the BlackBerry Pearl, Pearl Flip and the Storm. Other features on the device include a 1.3MP camera with video capture, speakerphone and being a messaging phone it also supports MMS/SMS, IM and Email. The T349 is to grace with its presence both T-Mobile's contract and prepaid line-up. No pricing information is available yet.
