There are a lot of reasons to like Republic Wireless, the forward-looking unlimited hybrid 3G/WiFi mobile virtual network operator that started an invite-only beta earlier this year. The invite-only part is not one of them. If you've been waiting for your chance to try out Republic's super-cheap plans, then you won't have to wait much longer: the company announced on its blog that it will soon be open to all applicants. All you've got to do is pre-order the company's only available phone, the Motorola DEFY XT, for $259. There's just one plan: unlimited (yes, really unlimited) talk, text and data for $19 a month.
