After T-Mobile and Google heard all the complains on 3G reception with the Nexus One and The double ETF, they are giving us some good news to existing T-Mo customers. Starting January 14th, existing T-Mobile customers can upgrade to Google Nexus One for only US$ 279. Customers that previously upgraded to Nexus One paying 379, will receive US$ 100 mail in rebate… that is better compared with Apple when they give iTunes cards as a rebate. Starting to today, Google will notify them if they qualify for that refund. Expect your 100 bucks withing 14 days.
