I've sent iKeyEx and 5-Row QWERTY (which isn't 5-Row nor QWERTY anymore :p) 0.1-8 to BigBoss. Yes this time is real.
iKeyEx 0.1-8 fixes a critical crash on pre-2.2 firmwares. Users of pre-2.2 users should upgrade to iKeyEx 0.1-8 (or just upgrade to firmware 2.2.1!). Hopefully all crashes will be solved soon so that I can end the 0.1-* chronology.
5-Row QWERTY 0.1-8 adds a lot of customizations. Pretty much of these have been covered on iClarified.
