High incomes still can't Roth IRA payins. Contributions are barred for couples with AGI of $176,000 or more and singles with AGI of $120,000 and up.

But there's a loophole:

They can make a nondeductible IRA payin for 2010 and then switch the IRA to a Roth and pay tax only on the earnings. They can do so for every year after 2010, too. But there's a trap if the taxpayer already has an IRA with deductible payins. In that case, the tax free portion of the Roth conversion is based on the ratio of nondeductible payins to the total of all regular IRA balances.
