The wait is almost over! After asking you guys if you received the Cupcake update, T-Mobile US just posted plans for the Android 1.5 Cupcake Rollout and it'll start by the end of next week! They're going to be randomly sent over-the-air so you may have to be patient in receiving the update, T-Mobile says everyone should get their Cupcake goodies by the end of May.
