[quote name='Zoglog']on another note, the damn new flash player sucks. It's only flash 6 so most content doesnt even work. And when it does the flash files are too big for the stupid memory hahah..... the PSP Browser is pretty pitiful unless you find sites suited only for it.[/QUOTE]
They really need to up the cache to allow whatever the size of your mem stick is. I can easily have up to 100Mb free, which could easily cache several hundred websites (probably even more).
If you do run into a site that gives the ole "Out of Memory" screen; back out of the web browser, head into another menu on the PSP (say Music) than head back to the browser, hit the history menu and head back to the site that was giving you troubles, it should re-connect to your access point and it should then load the page properly (probably).
