Recently bought the HTC Hero Unlocked White Teflon version. Had an iPhone 3G with the unlimited Data/ Text plan. I called and asked them to enable the MMS feature early since it is blocked for iPhone users. So they dropped me down to a regular data plan which did not work. Then upgraded me to a smartphone data plan. And I called again to reactivate to an iPhone plan. Called numerous times. Reinstalled the sim on the iPhone data is active. I have done all the usually remove sim card/ factory reset. About as much as I can do on a mac OS wise. They still cannot seem to get my data to work. Any ideas. Much appreciated.
