If that's too much money, most carriers will let you store your contacts on their servers for $2 to $4 a month. (Verizon will even do it free if you sign up for the company's online billing plan.) Finally, if you're dead-broke, you can use Apple's iSync (if your phone is supported) or software called BitPim (bitpim.org) to transfer your contacts to your desktop for free. Or nearly free—trying to use BitPim via Bluetooth crashed my computer, so I had to buy a $30 cable to do the job. Of course, any of these options beats spamming your friends and family for their phone numbers, not to mention the tedium of data entry. Trust me.
