How would you recommend I transfer all my contacts from an LG phone to iPhone?

You should be able to export your contacts as a .csv file.

If the iPhone doesn’t understand that, then everything I’ve ever suspected about Apple is true.

If your contacts are synced with your google account this will be a piece of cake. Google uses Exchange protocols to sync mail/contacts/etc with iOS devices.

Instructions

You should also be able to sync your contacts into Yahoo if you have an account with them, then you can sync your Yahoo contacts right to your iphone through itunes.

Ok I have a great recommendation in case anyone runs into this problem. I was lucky that I had all my contacts sync’d to Google from my LG Optimus V Android OS/Google Phone.

So from iPhone go to

1. Settings
2. Mail, Contacts, Calendars
3. Go to Add Account
4. Tap Microsoft Exchange
5. Enter your Google Account E-Mail handle
6. Enter the password to that handle
7. In Server field enter m.google.com
8. Follow up with your User Name (Gmail handle) + Password
9. Then toggle Mail, Contacts, Calendar On. (If you admired your previous lists that is)

*Note after each number you pretty much have to hit Next on the iPhone unless the fields in the next steps are shown.

It’s also important to turn off Gmail under Settings>Mail, Contacts, Calendars before using Exchange. Then once your contacts are on your iPhone select Exchange from Mail, Contacts, Calendars then turn off Mail and Calendars (Or leave everything on Exchange on and turn off Gmail, which I don’t recommend because the Gmail app is much more powerful than the Exchange app when toggling around with Gmail)
