The palm pre + vodafone provide rom 2.1.0 but for some reason my network service provider do not allow my phone to operate in this rom. I can't send sms or call, when I go to SIM section, the devices says it cannot read info from SIM. I read that there are some people of my mobile network get it works with rom 2.2.4. I don't know how to get that rom for my device. Some one can help? Or give me instruction to fix the error that stop my device from call or sms in rom 2.1.0. Thank you very much!
