Can I exchange iPhone for one with more storage?

[rcossy1023]

I recently bought a 4gb iPhone and I realized that an 8gb would be more suitable for me.
Im still within my 14 day return period and I'm aware of the restocking fee but I do not have a receipt.
Do you think the guys at the Apple store would allow me to upgrade to the 8gb and I pay the difference?
