Ok im new to this iphone stuff been a berry user for years so why is firmware 3.1.2 better than 3.1.3 srry about this dumb noob question have sympathy??
iPhone OS 3.1.3 software update, features various minor bug fixes and improvements, including improved accuracy of reported battery level on iPhone 3GS and resolved issues with third-party apps not launching.
your ok b/c your on at&t as for me it would be a bad move in my part b/c im hacktivated and running tmobile...so for ex for me it would be pointless to update.
