I also have the 4.0 software running on my Verizon 7750. I just installed it last night. Do you think your 7750 BB runs slower with the 4.0 software than it did with the 3.7???
I'm usually paranoid with software flashes and wonder if it took correctly. In addition, I talked to Verizon on the telephone just two days ago and they said that although they can enable a provisioning on my account for the WWW it doesn't mean it will work....
So basically, I was told a modification was made to the provisioning on my account which would enable the WWW if I setup the gateway on my BB correctly. I still do not have web browsing... but I do have the 4.0 OS running....
In addition, as per the instructions for the 4.0 upgrade, I did delete the vendor.xml file from the appropriate directory... after the upgrade, the vendor.xml I see is basically an empty file. Do you have a vendor.xml that actually lists the 4.0 OS???
---More help for WWW on VZW 7750 BB please!
