Hi all. I was wondering if you could help me out with a little mystery I'm trying to solve. I noticed that the 1st generation iPod Touch (not the new thin one just released) has 2 distinct serial numbers MB376LL/A and MB376LL/B. Can anyone tell me which of the 2 serial number iPod Touches contain the complete array of applications including the Stocks, Weather, Notes, etc applications? Which one lacks the full set of these applications and which one only has the bare minimum apps? Thanks for your time and input!
