I have an UNROOTED HTC Hero running firmware 1.5 - got the 2.1 update on my computer and have not installed yet because I want to know if this will screw up my phone since Sprint is NOT my carrier. My service is through Alaska Digitel/GCI based here in AK. Another question: Are you supposed to remove the SD card from the phone before running the exe file to update to 2.1? Anyone familiar with how this would work?? Thanks in advance!
