I recommend a dedicated cell and e-mail account for your search – you want both of them to last longer than your search.
Using a work cell or e-mail will cut yourself off to all the networking contacts you’ve made once you change jobs. Also, you may not be able to take your cell number with you when you leave.
A dedicated e-mail is helpful so you don’t mix up important networking e-mails with kids soccer, book club, etc. Also, an e-mail that is just your name looks more professional.
LESSON LEARNED: I’ve got 500 business cards with my old work cell number if anyone wants one – I found out after I had them printed that our corporate agreement did not allow me to take the number.
