Cellphone unlocking for dummies

NokiaFree screenshot Say you are going to travel to Europe, but are unwilling to pay the insane roaming fees that some functional monopoly imposes in your country. So you buy an overseas GSM chip and drop it into you phone and it just works, right?
Your carrier is probably unwilling to let you use the phone you’re leasing from them -and even the one you outright bought from them with a nice markup- in some competitor network. Any competitor network. Even if it is half a world away.
Well, there’s help out there, and there is hope:
NokiaFREE calculator will provide unlocking codes for the most popular models from a dozen manufacturers, either online or in a standalone version.
However, if you succumbed to temptation and bought a Treo 600 just five months before the Treo 650 was released in your country, you might have to reflash it under your own risk.
Update 20050910: In an article aptly named 20 Things They Don’t Want You to Know, PC World writes about cellphone unlocking, but fails to even notice NokiaFree.

Palm RAM Backup

As it happens, Magda’s Sony clie has a backup-to-memory-stick feature that is a proven lifesaver. Not to be outdone, I found two open source backup programs that perform that same task in the Treo 600 -or any other PalmOS handheld with a flash memory card, for that matter- Red Feline Backup and VfsBackup will back everything in RAM to a folder in the card, but I like VfsBackup a bit more because it will copy only those files that have been modified since the last backup. I guess now there are no excuses to back up the PDA often.
