ZIP owns or leases tech? 2G & 3G cut off?

Reposting below as query may go unnoticed in the other thread title relating to Brett Lee where I read a user comment that Ziptel may be leasing the technology:

Is it true re: Ziptel leasing the technology? According to their website they have developed and "wholly own" the technology.

Ziptel first came onto my radar when its SP was 0.40. Since I was not very familiar with the company and various contradictory comments were available, I thought best to monitor the company periodically.

Obviously, in hindsight, it would have been extremely profitable (in terms of capital gain) if I had purchased stock at that entry point. But risk profile was not clear at that point in time.

I am looking at making a purchase into the stock as it seems well placed, with the global launch and well-positioned marketing, to make more gains (even if more modestly in terms of rate), but I would intend to hold the stock for the next few years at least.

One other query I have which fellow forum users may provide some insight: In terms of the current moat of comparative advantage possessed by Ziptel seems to be their excellent use of bandwidth and applicability into markets which are less developed, what happens if/when 2G and 3G technologies are switched off at various points in time where some are touting could be as early as 2016, whilst others 2020? I would presume that Ziptel would then strive to develop similar compression programs into technologies of the time. Otherwise, Ziptel would only be a medium term investment opportunity at best.

Any thoughts?? Thanking all replies in advance for their appreciated input.
