iPhone or xBox 360?

My birthday is coming on the 6th May! ( YAYAYYYYYYYY! )

I have a small problem to solve until then and I won't stop thinking about it until it's solved ( which becomes another problem ).
The problem is: What should I ask for my birthday? An iPhone 3G or an xBox 360?
Sometimes I'm sure I'll get an iPhone because it's from Apple and it's an fantastic alternative for the regular Windows Mobile. But when I read my gaming magazine and I see a new game coming for the xBox I just go nuts!
Anyway, the price counts as well, here in Portugal, an xBox 360 Elite System with 120 GB costs 400€ and the iPhone 3G with 16 GB from Vodafone cots some astonishing 600€ which makes me join the dark side ( well, the xbox side! ).
The other thing that I'd like to mention is the fact that the T-Mobile G1 hasn't come to Portugal yet and when it comes it will surely be cheaper and I'll surely want it which gives the xbox another point.
But when I think of the iPhone... omg I'm so unsure!

Please, help me to decide by leaving a comment with your reasons to get an xBox or an iPhone.
