Ah, lovely. Why did you buy a N900 in the first place? Because none of your friends had one?

If you've been hanging around on this forum for this long, it amazes me that you'd still choose a device purely based on what you consider most impressive to show off to your friends. Maybe you should glue fake diamonds on your N900, that might drop some jaws.

Enough trolling, just go away and buy a custom iPhone or some other fashion accessory that goes well with your Gucciprada handbag

EDIT:
On a more serious note, if you want to truly make a safe decision and sleep well at night without any fear of one of your friends buying the same phone, make your own:
