flood of leaks, Verizon's just officially announced its prepaid data plan for smartphones. The new 3G Prepaid data package will offer smartphone users "unlimited" data for $30 a month, while feature phone users can score 25MB of data a month for $10 with a 20-cent-per-meg overage fee -- all contract-free, of course. The prepaid smartphones include all of Verizon's Android phones, the Pre and Pixi Plus, as well as most recent BlackBerrys, which is a pretty solid list of choices -- and you can sign up for them today or online on September 28. Of course, you're still on the hook for a full price phone and a voice plan (and there's no mention of texting), so whether or not this works out to be a deal is up to you, but we're definitely seeing the prepaid data market start to significantly heat up, and we like it. PR with full device list after the break.
