PPCGeeks - switching between WIFI and EVDO

I, too, have had similar issues.

I upgraded from an out-of-the-box unit to a GPS enabled device - via a sampling of the 3.35+ Radio and the 5060+ ROMS when trying to access a non-WiFi internet connection - via Network Connection.

Although my PHONE continued to work fine, and I could send and receive instant Text messages... I could NOT send or receive ANY MMS or SMS transmittals. I could, however, access my email and the internet - via WiFi (at first), but - when I attempted to connect to same via Verizon Wireless... my Verizon VX6800 starts to connect via the #777 access, but will show an empty Password box on the Network Log On page (in other words it doesn't save the Password from a previous attempt - even after I type "vzw" and check the box).
At first - we were receiving error messages that said: "Error Code 11; PPP Connection Error" and "Network Connection Failure".

I can not begin to tell you how many times we took the battery out and did hard resets. I've even returned the device back to the original settings (ROM 2.09.605.8; Radio: 1.30.60) and - with the exception of the "Error Code 11" and PPP message... STILL have these connection issues.

Countless calls to Tech Support have finally put me in touch with one Ian Chamberlain... a most sincerely concerned, patient and articulate tech dude... who went the extra mile, and then some, to troubleshoot the problem. Yes, (as with all the others) he knew from the start that I had cracked the OS and upgraded from 6.0 to the much more desired 6.1 - with the needed GPS... and he STILL was willing to try to help.

In the course of his investigation, we discovered (much like that of a few fellow PPCGeekers) that there was a Network setting (on Verizon's end...) that somehow required "resetting". Foregive me, but I've forgotten just what it was called... a DMU setting... I believe. Anyway... once that was preformed, we no longer received the afore mentioned "Error Code 11, etc." message - and now ARE able to receive MMS messages... but, still are NOT able to send or receive email OR access the internet on anything other than WiFi. A direct EVDO connection takes us to the Logon to Server page.

Thinking it may NOT be just be this device, Verizon has kindly offered to send us a NEW, out-of-the-box device (rather than a referb unit)... knowing I'm going to attempt to upgrade it. The current belief is - that in addition to the Network Connection Switch issue, we previously may have unwittingly been given replacement phones (from our local Verizon Wireless store) that may have been part of a "bad batch".

Once the new unit arrives (sometime tomorrow) I'll try it "as is" - in it's natural form... both via WiFi as well as direct - with a Network connection. If that works without flaw, as hoped, then we'll attempt to upgrade to the 2.40 boot loader, then the more stable 3.35+ Radio and N2C 5060 ROM... (that is, unless any of you have a better, more reliable suggestion).

More to follow.
