Dead Phone

I don't know what happened but my phone broke.
So, I am using my phone yesterday and the screen is white. It's a flip phone so the front screen seems to work intermittently but overall, if I press any buttons or open it, everything goes white.
This means I cannot see texts, I cannot send text and unless I have a number memorized I cannot make calls. As an avid texter, I am a bit annoyed.

So prior to the phone dieing, Brian had sent me a text asking to meet me for lunch. In the middle of texting him back, the screen went white and I had to type blindly, having complete faith in my fingers and my t9-word.
He texts me back but I can't read the text.
Fortunately, a few weeks ago Brian and I had discussed our phone numbers and came up with a way to remember his in the event that we didn't have our cell phones. They way he told me to remember his was because the last 4 digits were 2428, because I am 24 and he is almost 28.
So I decided to call him and let him know the situation.
I dialed up the number from my office phone since I wasn't sure if my phone was working at all. I didn't expect him to pick up because he was at work so I wasn't surprised when it went to voicemail. He has an automated voicemail that is just a women's voice saying you have reached this number. For a brief moment I worried that I had dialed the wrong number, but I figured, what were the odds that someone would have a similar number and the same automated voicemail. So I left a message explaining that my phone didn't seem to be receiving texts and to call me at the office.
About an hour passed and I hadn't heard form him. It was just about lunch time so I decided to call again, this time on my cell phone, thinking that maybe he ignored the first call since it was from an unknown number. Once again it went to voicemail and once again I left an elaborate message about how many phone isn't receiving texts but apparently I can receive calls and if he still wanted to go to lunch he should call me back.
Well, I continue with my days work and go to Julies office for a little while to chat. An hour goes by and I decide to randomly check my voice mail since I can't see if anyone has called but perhaps Brian has, and he did. So I hit the proper keys on the phone to return the call. This is when I find out that Brian's number ends with 2824, not 2428...

Sorry 2428 for all the calls that don't make sense...
