Query: Sony is #1 for cell phones!

Great device. Pictures are amazing for a phone! MP3 player could use a little help. Screen is beautiful, and as always menu interface is a treat. The phone is Java 2 compliant however many programs that run in the background will not notify be able to notify you unless the program is open. i.e... Mig33. Very other than the MP3 player, and Java notification issues the phone is a 5!
