While Sprint and T-Mobile have already announced their release dates for the Samsung Galaxy S4 , we’re still waiting on formal word from other carriers. That includes AT&T, the nation’s second largest carrier, who started accepting pre-orders of the device yesterday. At that time, AT&T’s site mentioned the device would be shipping by April 30th, but those estimations are always subject to change and we just haven’t been comfortable accepting that date with open arms.

A new leak suggests AT&T’s Galaxy S4 will be available a few days sooner than that. This internal document from a RadioShack employee reminds staff that AT&T’s Galaxy S4 will launch April 26th with a price tag of $200. Note that this could only mean RadioShack will be offering it that day: AT&T could still be getting it even sooner than that.

The same document lists Sprint’s version for April 27th, which we now know to be official. It seems we can put a higher degree of trust into this, then, but we still won’t pass that off as fact until we hear it from AT&T ourselves.
