Samsung have "confirmed that it will immediately sue Apple if the latter releases products using advanced long-term evolution (LTE) mobile technology". IP research firm iRunway, earlier this year found that Samsung fully owns 10% of all LTE patents issued so far, meaning that they are definitely putting their money where their mouth is.
Now, Apple would be a bit stupid, and far behind the times to release a next-generation iPhone without LTE, so this is going to get very, very interesting. If they release the new iPhone with 3G only, we'd be looking at waiting nearly an entire year before they release another phone, which would still not include 4G. Apple don't have many moves to make here. Another thing to consider is that the Cupertino-based company already has their iPad with 4G capabilities, have Samsung been waiting for the new iPhone before they pounce?
