Connecting to the Net using two Nokia Phones at once

I own two nokia 5130c-2 Xpress Music. I would like to know if there is any way to use both the mobile phones to connect to the Internet at the same time so that i will get double the speed. I use Windows 7 and can switch to linux if needed. Please suggest the whole procedure in a step by step approach since I am new to computers.

I have tried using nokia pc suite but it allows only one active connection at a time. Using standard dial-up connection and nokia pc suite at the same time won't work either. Please computer geeklords help me solve this problem. Isn't there any way i can combine both the connections.

Thanks in advance
