For those of you who have installed the new custom firmware 3.51 M33 may have noticed that homebrew applications that use Wi-Fi were not working correctly. As a result, the M33 Team have made a patch to fix the problems. Apparently, the problem was caused by Sony’s 3.51 wlan.prx code and not by M33 code.
The 3.51 wlan.prx reportedly affected the 1.50 wlan.prx, stopping WLAN-based homebrew from working. As proof of this, they pointed out that the 3.40 wlan.prx did not have the same problem.
