I'm pretty sure accessing anything from your mobile phone will be fairly secure.. if your accessing it via a WAP Access point gateway, then your IP is proxied via the cell network so you dont even have an external IP. If your accessing it via an Internet Accss Point gateway, then you have an external IP but you will need another layer of security such as a VPN tunnel or such.. But the first method, such as Wireless Application Protocal *WAP* should be just fine, I have used it like that in the past.
