Engadget is reporting that Verizon Wireless may switch to tiered smartphone data plans — similar to AT&T — starting on July 29th. The blog cites the same source who is prognosticating an August 12th release of the DROID 2 (along with some sort of Star Wars limited edition version with R2-D2 on the back). No details on pricing, data caps, or terms were listed in the report. We don’t have to stretch our minds very far to imagine this happening, but let us hope this piece of intel retains its rumor status well past the 29th. We’ve reached out to Verizon for comment and will update if we hear back. Thoughts?
