What did you use it for in that time?
The ideal thing to do with any electronic when you first get it brand new is to charge it 'til it's 100%, then use it until it dies (do not charge it again until it dies!)
THEN after an hour or so charge it again 'til it's 100% and again let it die by using it...this way you will fully use the battery and throughout it's life it will give you maximum charge.
Just to clarify, you aren't saying that you should let your phone die each time you charge it, are you? Because while that may have been good advice back in the days of NiCd batteries, it is terrible advice for Li-ion batteries. You will need to do a full cycle to calibrate the battery meter, but thereafter you should charge at about 50%. Recalibrate the battery only every 6-12 months or when you feel that it is giving you an inconsistent or inaccurate reading. Running a Li-ion battery like the one in the iPhone to zero every time will dramatically shorten its battery life.

As a comparison, mine's currently at 54% and that's after 4 hrs 7 mins usage (mainly calls, but with some texts, Twitter, and iPod usage mixed in) and 22 hrs and 14 mins standby.
