I would recommend installing SSH, even if you dont plan on using it. It will come in handy when the day comes that you freeze your phone. Just make sure you remember your IP. SSHing in and renaming the applications folder is the simplest way to get a frozen phone to boot up without having to restore. So my advice, Download openSSH from Cydia (there wont be an icon, so you wont notice it) write down your IP somewhere. And forget about it, until that day your phone wont turn on...... and that will happen.
