- No tethered use as a modem for my laptop. This seems to be a deliberate decision to keep the operators happy.
- No IMAP IDLE support - again I suspect deliberate in order to drive folks towards the subscription based MobileMe service. There is at least one app out there that addresses this though it isn't an official app and so require jailbreaking the phone.
- Can't mark emails as read without actually opening them - that's a biggy!
- Uncertain how well it will work with SyncML based OTA sync services such as ScheduleWorld and MyFunambol - though there is now a free funambol client in the app store I understand.
- To get an ssh client at present requires jailbreaking - OpenSSH.
- On screen keyboard as opposed to blackberry style physical keyboard - though have generally heard good things from folks who have tried it.
PS. The latest carnival is up over at the Mippin blog.
