Add Call button goes dim before I can make a 3-way call
I'm a newbie to this site, and also a new iPhone user, having gotten my iPhone 5 3 weeks ago.
I'm discovering a problem with the phone app. I need to be able to make 3-way calls into a chat line I'm working with. Whether I dial the line's number manually, or from contacts, I get the same problem - the "Add Call" button usually goes dim before I can initiate a 2nd call.
Typically, the button stays available from just a few seconds, up to, at most, 10 minutes - usually, though, it tends to go dim from between 1 and 3 minutes after initiating a call.
I've also tried calling a local automated weather service number in my area, the new number for TellMe, and even my land-line and I get the exact same behavior. I'd think that button shouldn't go dim for any old reason - it should be there whenever I need to make a 3-way call, whether it be conferencing with 2 friends, two family members, etc.
When I call the chat line, I connect, go thru my signin procedure, then double-tap the "Hide Keypad" button, then I'm ready to initiate the 2nd call.
FYI, I'm a Verizon user, using iPhone 5, and iOS 6, I add all my contacts to my phone using Address Book on my MacBook, I'm currently on 3G, as 4G LTE hasn't made it here yet, and my signal strength is usually between 1 and 3 of 5 bars. I'm also on the Share Everything plan with 300MB of data. Also, I just did a hard reset on my phone, using the holding power button plus home button combo, and that didn't seem to help either.
This problem is really starting to frustrate and puzzle me! I've even spoken to a tech with VZW, as well as a lady from Apple, and they're just as puzzled as I am.
If *anyone* knows *anything* about this problem, your help will be *greatly* appreciated!
I've got Dropbox installed on my MacBook, and, every time I plug my iPhone in to sync and/or charge, the Dropbox window seems to pop to the foreground, and VO says "Dropbox has no windows." I'm currently running Mac OS 10.7.5 and I believe Dropbox Version 1.4.12. Any ideas as to why this happens? This has happened, ever since I plugged my iPhone in for the first time. Strange behavior, if you ask me.
