I have also noticed a problem with the iphone. As a physician I receive my pages from the answering service via text message. Hoeverver, on my previous phone I had asked the answering service to add *67 in front of the number so when I called the patient they could not see my number. However, with the iphone the *67 is in front of the patient's number but is not highlighted blue or underlined in the text message. Hence the number is not blocked. Any help would be of assistance. i do not want to block my caller id under settings each time as this is inefficient and time consuming.
