Unless one is a doctor/EMS/Hatzalah or has a sick family member, there should be no texting, tweeting during davening. So disrespectful to your fellow congregants (men and women) and especially to Operator Himself.
BTW, our kavanah is between HaShem and ourselves. Let’s not judge anyone…..
Charliehall: Eyen Roeh. How would anyone know what is on your Blackberry? I would think that you are texting/tweeting during davening. Siddurim cost a lot of money that shule’s pay for. Use them.
