How to migrate accounts and data from one Android phone to another?

I have a HTC Magic phone with Android 2.2.1 and I want to migrate all accounts (9), apps, sms, settings, etc... to a new phone with Nexus One. Do you known some Android service/option or free app on Market to do it? Thanks a lot! **UPDATE** I have migrated successfully :) Old phone: HTC Magic rooted with Android 2.2.1 New phone: Nexus One rooted with Android 2.3.3 * At first, backup google accounts with Titanium Backup Rooted * Then, backup SMS and Call logs with Life Saver 2 * At end, restore in the new phone Some problems with settings restore (Wifi, Bluetooth, apps, etc...). Thanks!
