Reading the comments at Bruce Schneier's blog, I came across this recommendation by someone where they write:
@Michael_H - Here you go, buy yourself a cheap Huawei G6620 on eBay, any network, doesn't matter which, then you'll want to go into Security Settings (5) Certificate Manager, now DELETE all the RSA tokens.. Then back out and goto web'n'walk service - settings (6) Trusted Certificates and DELETE all RSA tokens.
Now your Telecom's provider has no way to access your device remotely @ ALL...
Can't see your contact's, can't access your Phone Book, Can't see you on there GPRS..
It looks like the person recommends Huawei G6620 because that phone allows the deletion of the RSA tokens.
Now assuming that the Telecom provider, or other parts of the government, use those RSA tokens as part of their setup to access data from your phone....
...wouldn't deleting them at most force the telecom provider (or government) to use a non-encrypted channel to access the data on your phone?
Or is there some other "benefit" against surveillance from deleting the RSA tokens?
