So you have a PSP and a Mac and you want to sync the two? The good folks at PocketMac, long-time providers of Mac syncing software, have released PocketMac for PSP. The new PSP version of PocketMac lets you sync either via USB or through a Memory Stick reader and will let you put your contacts on your PSP, even though the PSP is not designed to handle them. Great stuff from a solid software developer. $10.
