Miemt11 from our forums has released his latest patch, MPH firmware launcher v1.3.7u4 for the PSP. Here's what the new version tidies up:

u4 version: (Only tested on Firmware Version 2.00)

1: L + SELECT to load the real/hardware original Sony UMD (Old way)
2: R + SELECT to load the real/hardware original Sony UMD (New way but unstable)
3: New method of loading the Sony UMD
4: No more L + R + SELECT boot methods
5: Internet browser should be more stable when entering web address (lesser hang does not mean no)
6: reduce eboot by 4KB ;( and some minor fix...

Please post your Internet browser is stable or not (On this u4 version). Any feedback is welcome.
