The P500 doesn't have a locked bootloader like the newer Optimus devices, however it does have a carrier lock. Once any device is unlocked from a specific carrier the device remains unlocked no matter what ROM gets flashed to the device. You could flash CM or AOKP and then back to stock if you wanted and the carrier lock would remain unlocked. All the carrier lock does it tie that device to a specific service provider ( AT&T, T-Mobile, etc. ). Once unlocked, since the P500 is a GSM device I believe, then that device can be used with any service provider that also utilizes a GSM network.
The reason carrier unlocking must be done from a stock ROM is the fact that any custom ROM won't have access to the devices hidden menu. The hidden menu can only be accessed thru the stock dialer app on a stock ROM. And the carrier unlock procedure is done via the LG hidden menu.
