If you have a "genuine" 5260 (part # 5260, 5262, or 5263) then you unfortunately do not qualify for this upgrade.

Efficient has discontinued the old 5660 and replaced it with the 5663, and then with the 5667. The 5262 is now the de-facto 5260 as well. There is also an "Extended Reach" 5262. Now there is also a 5263.

The hacks will NOT work on 5262, normal nor extended reach, nor will they work on a 5263. Note that you cannot buy a 5660 anymore at any place besides Ebay, nor can you buy a 5260, as both models ceased production some time ago.

Only certain part numbers have Telnet available. See the chart below for details on a few popular numbers.
