Conflicting Reports
eWallet: (lack of automatic keyboard appearance at login screen, works for some)
Truphone: (out of memory error/ memory leakage from other app? works for some)
What's On: (fails to discover TV stations upon entering zip code/ works for some)
Note: One commenter on toucharcade forums RPGGuy claims the 2.1 firmware no longer plays 8 bit sounds correctly which may explain the many sound glitches in some apps.
Note #2: It appears as though applications which prompt for a password upon launching unreliably present the keyboard for password entry. Both SplashID and eWallet appear to have the same issue. However tapping the password blank brings up the keyboard manually.
