T-Mobile has made a micro SIM card available that will fit into the Apple iPhone 4 and Apple iPad. People who have an unlocked iPhone 4 will be able to use this micro SIM card with their device to access voice and data services through T-Mobile. T-Mobile explains, "Already have [an] iPhone that you need to activate? Just get a micro SIM card and choose a plan. Slip the ready-to-use micro SIM Card into your [iPhone] and you're ready to go." The micro SIM card is free with a new agreement. iPhone 4 owners who choose to use their device on T-Mobile's network will not have access to 3G services, as the GSM iPhone 4 doesn't support T-Mobile's 3G/4G spectrum frequencies. It will be limited to EDGE data speeds.
