UPDATE (04/19/2008):
1. Unfortunately, it seems none of the Jbed 3.1 versions are able to run Opera Mini 4.1 beta
on touchscreen-less MS Smartphones (but NOT on Pocket PC's!!!) if you switch to other apps (for example, the home screen) and, then, back, you will no longer be able to control Opera Mini. I've tested this on my WM5 s310 / Oxygen (major problems) and, with HTC's recently-released ROM upgrade, upgraded WM6 s710 / Vox (not that frequent problems but still annoying). At XDA-Devs, other people
have also reported the same problem with their Smartphones.
If you do encounter problems like this and can't refrain from task switching, you'll want to downgrade to the
Cloudyfa 2.1 version available
HERE. Note that it can safely co-exist with 3.1 if you've installed the latter in another directory (for example, on a storage card or a flash disk) - then, it's only the file associations that will be needed to, say, quickly switched if you don't want to manually deploy a MIDlet from inside the GUI of the specific MIDlet manager. That is, you don't need to delete Jbed 3.1 if you plan to keep it for example for M3G gaming.
Note that touchscreen-equipped Pocket PC's do NOT suffer from this problem!
2. Ebenezer has released a fixed version of his
Jbed 3.1 MIDlet manager
HERE. Now, it does create a link file in Start Menu / Programs on both Pocket PC's and MS Smartphones. It also installs to any target media (not only "Storage Card"s) without problems. Note one caveat, though: the link file (the one the installer puts in the Start menu) has
\Storage Card wired in, which doesn't work with any storage card (or flash disk) named other than "
Storage Card". Hope this is fixed some time; in the meantime, just manually edit the link file to have the correct path.
