Chosen Solution

I have a i5 processer, i would like to upgrade to a i7 :P. Simply want to ask if that’s possible

No, the CPU is soldered on board. It would be more efficient to actually purchase the i7 MacBook Pro (known as MD102, while yours is the MD101), transfer your HDD or data over, and resell the i5, than try and switch between soldered processors (regardless if technically feasible or not).
