I have always been a fan of ESET products. Currently using Samsung Omnia I900. Try loading the beta version of the ESET anti virus for mobile phone wm 5 and 6. Everything works fine except that when I tried to taping onto the phone book icon it freezes. I think it might be a bug. I am kind of disappointed though by the lack of installation options as it only can be installed on the device memory which is kind of small. Hope that in future the installation can be done onto the storage card or onto my storage as in the case for Samsung Omnia I900. Secondly I would like to suggest that a firewall to be included like that for the PC version ESET Smart Security.
