Sprint says they don't know of any issues. Recommended I try online, so I found this site. I swapped out phones on Fri, as usual to use the Market place app I have to enter a gmail account including the password. I don't use this account accept for one source. I don't access it online thru my computer. So the only place I am using my Gmail is thru the phone. On Monday morning I had a message on the phone that my gmail password was not valid. After numerous attempts I went on line thru my computer to Gmail and had a message saying my account had been shut down for abuse, I had several bounced emails so I changed the password. All was well and now I am seeing bounced emails again from last night, the only place I have the password entered is on my phone. Anyone know of any possible way they can be hacking my phone? Is there a firewall program we can download to prevent such occurances? Thanks for any input.
