I have been using a Samsung Captivate on AT&T for about 10 days now. Ive had the email client break 3 times during the last week. I can see all the headers and even send email. If I try to open an email and read it, I get an error (The application Email (process.com.android.email) has stopped unexpectedly. Please try again. The only way that i have been successful in getting it to work again is to perform a "reset to factory default" which looses everything! I saw posts from Nexus owners that say you can delete email data but that doesnt help on mine..... I initially thought it was caused by downloading apps from the market. I've gone 6 days without getting any new apps or updating existing ones and I just got hit with the email error again... I have both my gmail and exchange email accounts active on teh phone. Any ideas? This is becoming a deal-breaker!
