smartphone for cheap? i had a sidekick lx before but now i have a new cellphone (the a1600 which is just a regular smartphone) and i want to know the cheapest way to get the same services as the sidekick plan on this new phone. the sidekick service plan had unlimited text, web browsing, email, and AIM messaging for only .99. i know it would never be as cheap, but... how should i get my money's worth with the new phone?
