Tmobile cheats existing customers via G1 I am very disapointed with this phone. It was designed to compete with the Apple Giant, though it was not given the feature set to compete. I am also sad that tmobile has embraced the industry practice of treating their existing customers like idiots, charging them extra for data services that could be provided under the existing $19.99 plan. Tmobile is telling me that I must pay an additional $24.99, on top of the $19.99 that I am already paying for data services. They report this is because the G1 uses its own data connectivity package (Even though it operates on the exact same band as the rest of their 3g phones). Existing customers beware, for your next bill may be very interesting.How can they justify this, when the entire point of a sim card is to switch between multiple devices?
