Aparently there is a MAJOR problem with bluetooth sapping the ROM out of the Hero and leaving SMS messaging and visual voicemail useless!! I got down to 12MB of Rom and my phone started acting WEIRD! I did a hard restore and got most of contacts that I had saved under google back, but can't receive texts or voicemails.. I am floored! Just when I was loving this phone it wants to go and pull this crap! I hope Sprint and HTC can come up with the solution fast or they are about to have a slew of Hero returns on their hands including mine! Man this sux major balls!
Ok so I finally gave up and took my Hero back to Sprint for an exchange. I now have the Hero that has "With Google" stamped on the back and Rev A where Rev 0 used to be..I am beginning to think all of the memory issues are on the phones without the google logo on the back. This phone works fine with my moto bluetooth H-9 HD and connects everytime as compared to my last Hero that didn't. No memory leak! YAAAAY! Also my battery life on this phone is a little better..I would suggest people who are having this same problem check to see if the google logo is on the back, if not take that puppy back to whinst it came!
