I ordered a N900 when my old phone broke. It is coming tomorrow but I can't activate with T-Mobile until next week for the following reason: I want to keep my phone number so I'll have to cancel my current carrier's account when I sign up for T-Mo. Before I cancel my current carrier I need to get to my voice mails, which I can't do until a new device arrives since my old phone broke. This device is being shipped to me and is expected next week, while the N900 is expected tomorrow, even though both were ordered off Amazon at the same time. My question is this: When my N900 arrives tomorrow, not activated with T-Mo, will I be able to use the WiFi ability with my home wireless internet connection and get online? Thanks for any help. I have been with Verizon for over a decade so I have forgotten how SIM cards work, etc or if it's needed prior to the N900 functioning. Ideally I'd like to get the N900 set up, enter phone numbers, download Docs to Go, etc even if I can't use the phone function yet until activating with T-Mo.
